Towa is and has always been one of my favorite spots for sushi. The fish is so fresh and you are getting quality over quantity. Watch out though because even if it doesn't seem like you have ordered a lot of food, the rolls are fairly big and the sushi portions seem to be double what they are at other restaurants.
One thing I highly recommend you try is the spicy salmon tempura roll! The entire roll is deep fried and cut into four pieces, served with spicy mayo drizzled over top and dashes of togarashi spice! Delectable! Keeps me wanting more! Towa doesn't take reservations, so if you want to get in on their delicious rolls, you may have to wait. Don't worry though, its worth it!
