elTacobar has gluten free items marked on their menu, and most items are marked gluten free. Staff is knowledgeable in answering questions. Be cautious though because my tacos were on the same tray as my fiancée - just happened to be all gluten free even though I am the only one with Celiac. Personally, I believe elTacobar is extremely overpriced!! $22 for chips, salsa, and guacamole is ridiculous, especially when most Mexican restaurants include chips & salsa for free. The tacos are small street size and priced around $9/taco and they require you to order a minimum of 2 tacos. The pricing of this restaurant is a Hamptons tourist trap!!
Chips are not safe, but the beef barbacoa bowl was amazing! Labeled menu and knowledgeable staff.
