I've spoken to a number of people who are gaga about this place, but I have been here twice and had completely different experiences both times. The first time I went with my husband, we ordered a sashimi appetizer that comes with a hot rock that you use to sear your own fish on top of. It was slightly messy but a fun experiment, and tasty. Then for our entrees, we ordered two different noodle dishes. I didn't especially enjoy mine, but I thought it was because I experimented too much with a peanut concoction. Husband loved his meal. This was also shortly after Lemongrass opened, and before it was discovered by locals and tourists alike.
The next time we went here we had a gift certificate. Hubby ordered a lobster dish (in fact, it was recommended to us by the giver). His lobster was tough and flavorless. Not a good thing for such an expensive dish! My dish was just okay, but nothing worth taking leftovers home for.
For such an expensive restaurant, I feel that Lemongrass should get their act together. Many people who love this place only order sushi here, so that may be more of their specialty. The sushi here is more expensive than most places, so I haven't tried it. Lemongrass is also guilty of crowding tables together. We were practically in our neighbor's laps on our last visit, and it's uncomfortable being so close to another party that you almost want to jump into their conversation and tell them to shut up. Of course the space is so small, that without crowding the guests, they wouldn't really be able to fit many tables inside. So perhaps outside seating is a better choice here.
Still, this place packs them in every night. Whenever I drive past, there are always tables full of people. So perhaps I've judged it too harshly. But I don't have the finances or the foodie patience to give it another shot for a while.
