OTOTO is a Japanese, $$ restaurant with a 4.6 Google rating across 717 reviews. With Blackbird check-in volume unavailable, that review base is the available popularity signal: diners mention izakaya-style sharing, sake, cocktails, and date nights or special occasions.
The clearest through-line is variety. Reviewers describe ordering across the menu without a miss, with specific praise for grilled squid and breaded oysters. Service may start slowly, according to one review, but the same diner noted the food arrived quickly once ordered.
