About Adios! by Oscar Diaz

Adios! by Oscar Diaz is a chef‑driven Mexican restaurant and bar created by James Beard Award–recognized chef Oscar Diaz and located in Terminal 2, Gate C17 at Raleigh–Durham International Airport (RDU) in Morrisville, North Carolina. The concept focuses on Mexican food with a Southern twist, featuring tacos, quesadillas, chilaquiles, arroz con pollo, and other plates that blend Southern cookery with Mexican roots, alongside an extensive selection of cocktails, beer, and wine.([toast.app](https://toast.app/r/adios-2400-john-btrantley-blvd/order?utm_source=openai))

A charge from this merchant typically appears when a traveler dines in at the Adios! by Oscar Diaz location in RDU or orders food and drinks to‑go from the restaurant, often processed via the Toast point‑of‑sale system (hence descriptors beginning with “TST*”). Menu prices often fall in the mid‑range for an airport restaurant, and charges may include food, alcoholic beverages, gratuity if added, and applicable taxes. In some cases you might see a small temporary authorization or a slightly higher pending amount if you opened a tab at the bar and the final total (after tip) was not yet settled.([toasttab.com](https://www.toasttab.com/local/order/adios-2400-john-btrantley-blvd/item-al-pastor-pulled-pork_7e36fd83-db22-49ac-bc10-4ada668db5e0?utm_source=openai))

If you have questions about a charge from Adios! by Oscar Diaz, first compare the transaction date and amount to your travel through RDU and any receipts or email confirmations from the day of travel. Because the restaurant uses Toast, you may be able to look up receipts or payment confirmations through Toast’s digital receipt links if you provided an email or phone number at checkout. If something still doesn’t look right, contact the restaurant via the phone number listed on its Toast ordering page or reach out through RDU’s dining directory, and your bank can assist with disputing the transaction if you cannot resolve it directly with the merchant.([toasttab.com](https://www.toasttab.com/local/order/adios-2400-john-btrantley-blvd/item-al-pastor-pulled-pork_7e36fd83-db22-49ac-bc10-4ada668db5e0?utm_source=openai))

Frequently Asked Questions

Why does my statement show “TST* ADIOS” or “TST* ADIOS 000183551 Morrisville NC”?

The “TST*” prefix indicates that your card was processed through Toast, the restaurant’s point‑of‑sale system. The “ADIOS” portion refers to Adios! by Oscar Diaz at Raleigh–Durham International Airport in Morrisville, NC. The numeric string is an internal terminal or location ID used by Toast and your card network.

What kinds of purchases typically generate charges from Adios! by Oscar Diaz?

Most charges come from sit‑down meals or bar tabs at the Adios! by Oscar Diaz restaurant in RDU’s Terminal 2, Gate C17. This can include breakfast, lunch, or dinner plates, tacos, quesadillas, sides, cocktails, beer, wine, and gratuity if you added a tip at the end of your visit.([toast.app](https://toast.app/r/adios-2400-john-btrantley-blvd/order?utm_source=openai))

Can Adios! by Oscar Diaz place a temporary hold or higher pending amount on my card?

Yes. If you open a bar tab or the server runs your card before you sign, Toast may place a temporary authorization that is slightly higher than your initial subtotal to allow room for tip. Once the final bill is closed, the hold is released and replaced by the actual final charge including tip. This may take a few business days to update on your bank statement, depending on your bank.

How can I get a copy of my receipt from Adios! by Oscar Diaz?

If you opted for a digital receipt when paying, Toast may have sent it via email or text—search your inbox or messages for Toast or Adios. If you did not receive or have misplaced the receipt, you can contact the restaurant using the phone number listed on its Toast ordering page or via the RDU dining directory and provide the transaction date, approximate time, and last four digits of your card so they can look up your check.([toasttab.com](https://www.toasttab.com/local/order/adios-2400-john-btrantley-blvd/item-al-pastor-pulled-pork_7e36fd83-db22-49ac-bc10-4ada668db5e0?utm_source=openai))

Does Adios! by Oscar Diaz offer any kind of subscription or recurring billing?

No. Adios! by Oscar Diaz operates as a traditional airport restaurant and bar. All charges are one‑time transactions tied to individual visits—there are no memberships, subscriptions, or recurring billing plans associated with this merchant.

Why does my Adios! by Oscar Diaz charge amount not match my food subtotal?

The final posted amount can be higher than the food subtotal because it typically includes beverages, taxes, and any tip you added when signing the receipt. If you opened a bar tab, a pre‑authorization may have appeared first, then later been replaced by the final total including tip. Always compare the posted amount with the copy of your signed receipt from the restaurant.

How do I dispute or question a charge from Adios! by Oscar Diaz?

Start by confirming that you or another authorized cardholder traveled through RDU on the transaction date and may have eaten at Adios! by Oscar Diaz. If the charge still seems unfamiliar, contact the restaurant using the details on the Toast ordering page or via the RDU website to request a check lookup and receipt. If you believe the charge is fraudulent or cannot be resolved with the restaurant, notify your card issuer and file a dispute following your bank’s process.([toasttab.com](https://www.toasttab.com/local/order/adios-2400-john-btrantley-blvd/item-al-pastor-pulled-pork_7e36fd83-db22-49ac-bc10-4ada668db5e0?utm_source=openai))

Can multiple small charges from Adios! by Oscar Diaz appear on the same day?

Yes. Separate checks for food and bar purchases, split checks among travelers, or repeated quick purchases (for example, grabbing drinks or snacks before boarding) can result in multiple small same‑day charges from Adios! by Oscar Diaz. Review each amount and your receipts from that travel day to match them up.
