The short answer
Toast documents TST* followed by a restaurant name for restaurant purchases. RIVERSIDE DINER is a retained example, not a verified venue. Compare the posted amount with your receipt; the prefix cannot establish authorization.
What do the parts of TST* RIVERSIDE DINER mean?
- TST*
- A payment-processor prefix this registry groups under TST* charges. The text after the asterisk usually names the specific business or product. Prefix guide →
What the restaurant prefix establishes
Toast’s charge-code table distinguishes TST*Restaurant Name purchases from business software and hardware fees. It does not identify the RIVERSIDE DINER in this lookup example. Treat the full wording on your own statement as a clue to investigate, not a location directory entry.
Toast says codes can vary by bank or processor. TOASTTAB and the other retained aliases are lookup spellings; this source review does not establish that every alias identifies the same transaction.

Pending authorizations, tips and posted payments
Toast’s merchant guidance explains that an authorization can remain visible alongside a finalized charge. A tip adjustment can also create a temporary additional authorization. Compare pending and posted status before concluding there are two completed payments.
If both payments are posted, ask the restaurant to inspect its payment records. Toast documents a merchant search using the card’s last four digits. Provide the date and amount through the restaurant’s appropriate support channel; its staff, rather than this website, can inspect the checks.

The next step depends on the actual problem
Toast’s duplicate-payment article describes investigating the restaurant records and correcting an incorrect payment when applicable. It does not establish an automatic refund entitlement or a universal arrival deadline for your transaction.
If you suspect an unauthorized debit or charge, CFPB guidance says to contact your bank or card provider immediately and keep follow-up records. A recognizable prefix does not replace that report.
Does TST* mean a Toast software subscription?
Toast’s table assigns the TST*Restaurant Name format to restaurant purchases and lists different codes for business software or hardware. The prefix does not identify the example venue.
Does a pending line beside a posted line mean I paid twice?
Not necessarily. Toast describes authorizations that remain beside finalized payments, including tip adjustments. Compare their status and ask the restaurant to inspect any suspected duplicate posted payment.
