Let's try another Mexican place - Gonza - it is one of the few restaurants I've seen on Open Table that has almost all five-star reviews! Management promises to provide a server who is well versed in the menu options that can be made vegan. And tequila? Bring on the margaritas!
As a courtesy, please consider your RSVP carefully, and only RSVP yes if you plan to be available to attend. If you think you may want to take leftovers home, please consider bringing your own reusable container(s). Finally, please remember that everyone is expected to order vegan food at TVSC event.
