Geisha has been the go-to Old Town sushi spot for my wife and I for many years. Their specialty rolls, like the "Korean Rocket" for example, are really unique and delicious. Geisha is often pretty busy and can be a tad loud, so if you're expecting a super traditional, authentic Japanese outing, you may want to consider going elsewhere. That said, the vibe is very fun, the private karaoke rooms are ridiculously cool and I've always found the staff (particularly the hostesses because we get take-out more often than not) to be very kind. If you're reading this, take my advice and give it a shot, I think you'll love it!
