Inaka, an eight-table Japanese restaurant specializing in ramen and donburi, opened at 72 Brighton Ave. in Allston a month ago in the former space of an Indian restaurant called Madina Market. The neighborhood offers a fair amount of ramen already - Pickaichi and Hanmaru are just a couple of examples - but early Yelp reviews of Inaka suggest that this newest offering is more than welcome. The ramen selection includes hiyashi chuka, cold noodles, for diners who don't want to burn their faces off in the coming warmer months. Also on the menu: gyoza, tempura purple sweet potato fries, a variety of hot ramen choices, katsu and curry dishes, and more. Inaka is open from 11 AM to 10 PM Monday, Wednesday, and Thursday; 11 AM to 11 PM Friday and Saturday; noon to 10 PM on Sunday; and closed Tuesday.
