This restaurant showed up today on my Foodler delivery list (misnamed Punjabi Palace), so I gave it a try. I ordered malai kofta and fish biryani, both Indian hot. Shrimp instead of fish biryani was delivered, which was the only misstep with the meal. I found the food--especially the biryani--fantastic, on par with or even better than places like Kebab Factory that I already considered very good. (A couple of days ago I ordered from India Quality, which was pretty good, but not this good.)
The biryani was the star. This is my favorite Indian dish when it's prepared well, but it almost never is. Most places seem simply to mix a lot of ingredients into rice and serve it, and the dish ends up slimy, but properly made (with a second cooking) it has a dry consistency, a twice-cooked flavor, and a fascinating complexity. Punjab Palace's version was possibly the best I've ever had, full of amazing complementary flavors from the twice-cooked aromatic biryani rice, very complex spicing, fresh vegetables, and ghee. The shrimp were very good quality.
The biryani was so good to me that the malai kofta, which was actually quite good, was an afterthought. IIRC I prefer the version at Kebab Factory, but Punjab Palace's was certainly above average.
I was very happy to see onion chutney and raita thrown in gratis. Both were fabulous and unique (the refreshing onion chutney was more oily than usual, the raita had nice cooling chopped potatoes).
Seems like the restaurant scene in Allston is smoking hot.
