I've ordered the vegetable dum biryani and bezawada/vijayawada biryani from Biriyani Factory before. I prefer the Hyderabadi dum biryani a little more, since the rice was fluffy and the grains were not sticky. Moreover, the choice of vegetables (melon, capsicum, cauliflower, carrot) were cooked in steam and did not appear to be the type that's from a frozen package. The biryani was neither oily nor heavy, and therefore easy to digest. It came with some mirchi salan, a savory gravy that tasted like a blend of peanut, tamarind, and roasted bell pepper. The bezawada was more rich in spices and fiery hot compared to the Hyderabadi biryani. Although it's the signature dish at Biriyani Factory, I probably wouldn't order it again since the rice and chili-marinated boneless fried chicken had a rough and dry texture, like almost fully boiled. I did appreciate the accompanying peanut salan though, it's very bright and bold. I think that this restaurant makes the best tasting side of gravy for biryani in LA, second to Paradise Pointe.
