We love the Mongolian pork ribs at Dian Xiao Er because (1) the pork ribs were really tender and juicy, unlike the really tough ribs served at certain tze char places in Singapore, and (2) the sauce had a wide array of spices, including curry powder, black pepper and cut red chillies! These spices really made the gravy flavourful although the dish can be a little spicy if your spice tolerance isn't that high.
We ordered the small Mongolian pork ribs (given the whole duck that we already ordered), but we were pleasantly surprised that the portion was fairly generous, since there were around 10 pieces of pork ribs! The dish was around $14++, which we guess is fairly reasonable for a meat dish at a restaurant.
