Name says it all as far as the menu goes - Lobstermans. While they do have a few token other things, 95% is lobster based. It is fresh, it is delicious, and they don't skimp on the portions. While I have never been to Maine, it is exactly how I would picture a Maine lobster shack menu to be like.
Located right on the water in Lake Las Vegas, the atmosphere is gorgeous. It is nothing fancy - more like a fast food type restaurant than anything, but the staff is very friendly, and the personal service was excellent.
Considering the main ingredient, prices are very reasonable. Most items $10 to $20. Lobster roll was $17, and so packed with lobster, I did not eat my bag of chips.
