I've been to Tsunami's on many many occasions. It's never my first choice for sushi in Mt. P, but I often find myself there because it is close to Palmetto Grande (movie theater next door) and they very often are offering a Groupon.
Tsunami's isn't the worst place in the world to get sushi, and it is certainly edible...but go somewhere else if you can. Actually, the sushi isn't my biggest beef with Tsunami's, its the hibachi. It is downright terrible. Please, if you find yourself at Tsunami's, do not get any of the hibachi dinners. The rice is really oily, and the grilled veggies and meat taste like propane.
I do have to give them some recognition for remodeling the space a bit and adding more tables. They used to have a stage at the far end of the dining area, that took up a lot of room. The service has also been better in more recent years. I don't know if it underwent a change in management but the servers are a lot more attentive than they used to be and I think the communication between the servers and the hostesses has also improved.
I cannot comment on the bar scene here, but every time we have gone in the past, it seems to be a busy section and a lively crowd. The bar area is ample and is sectioned away from the main dining area. They have some covered outdoor seating, which I believe is mainly used as a smoking section.
If you are specifically looking for good sushi in Mt. P, try Locals Bar or Tropical Sushi. If you are out to have some OK sushi with some cocktails, then Tsunami's will fit the bill just fine.
