I went at 14:30 on a Monday and despite the low-traffic time of day I risked the buffet. Everything I tried was very good! Even the okra, which I don't usually like, was beautifully spiced. A huge surprise: the masala chai wasn't oversweetened! Definitely coming back.
Update: I continue to go here whenever I'm nearby. Every time I'm really pleased by the quality of the flavours. One of the tastiest Indian restaurants I've found. Just one thing: the bathroom is, um, slightly "authentic" ;)
