Tenkai Ueno Ekimae is an izakaya in Ueno, Tokyo, serving sashimi, sushi, tempura, and yakitori. The seven kinds of sashimi are thick-cut, the five kinds of tempura are thin and crisp, and the skewers carry a light charcoal aroma. All seats are private rooms with tatami flooring and space to stretch your legs, and orders are placed on a tablet. When orders pile up, food takes a long time to arrive.
