It's a small, out of the way place that locals love and for a reason. The food is reliably delicious, the service is attentive and the prices are more than fair. I'm a celiac and get the spicy pad thai with chicken all the time for lunch here. Never had an issue. I've also had the basil fried rice, drunken noodles and massaman curry with duck. All were absolutely tasty. ALSO, you can buy beer and cider here. So, that's a bonus.
Want some reliably tasty Thai food from a locally owned place and maybe also a beer? This is your best bet in Central Square by a mile.
