Thai Tai is consistent quality, they're open late, prices are good, and the bubble tea is amazing!
I'm very dairy intolerant, and unlike some other places that just use powder only (and say yes yes it has no dairy when most all powders do--most places routinely add sweetened condensed milk too, you have to really be careful), Thai Tai use good natural ingredients (i.e. real fruit) & will make you dairy-free bubble tea if you ask them.
The only reason I didn't put 5 stars is because they ALWAYS put cheese on everything without asking the customer. Very odd as with traditional Thai food that would never happen. FIne, put the cheese on -- but then PUT IT on your menu for all to see.
Then those of us really allergic don't keep having to ask for "no cheese please" after you've already made our food!
All in all, Thai Tai is an awesome institution. Especially for late night hunger attacks ;-)
