Pasta e Pasta by Allegro is a Japanese-style Italian restaurant in Little Tokyo, Los Angeles, serving mentaiko, uni, and squid ink pasta. The mentaiko cream and uni cream are the signature dishes, and there is also a bacon and mushroom pasta in a Japanese-style soy sauce. Bread and a small salad come with the meal, and a line forms before opening with long waits during prime time. The space is small and few tables seat four people.
