So I took the recommendation (http://chowhound.chow.com/topics/640048) and went to Canteen. Quite nice! Thanks!
It was quite small. In fact I was expecting it to be small and was still surprised. Maybe 20 seats tops (7 counter, 4 tables)? That said I didn't feel cramped at the counter for one second. I liked the feel of the place too.
Service was prompt and professional. It was certainly "go go go" for the wait staff as I understand there are three sittings a night. From what I could see it runs like clockwork. I don't think I saw them take a break during the entire service for more than 30 seconds. That said, they were still attentive and friendly.
Dinner was three courses with an amuse-bouche. I can't remember all the little details but here goes.
Amuse was a small piece of halibut (served raw) with fennel shavings. Nothing spectacular. But I'm not a fan of halibut.
The brioche/bread they serve was buttery good. In fact so buttery I'm surprised they offer butter with it!
I started with a prawn salad with avocado. Nice & refreshing with toothsome pieces of avocado. I was going to try the other starter which was a poussin (spring chicken with some type of fig & polenta I think) . It also looked delicious but in retrospect probably too heavy for what I was having as a main.
Which was a lamb shoulder confit, with cranberry beans, onion relish and pumpkin seeds. Man, that was a good lamb. Tender, melty...mmmm.
And for dessert I had their house special, vanilla souffle. I'm not a fan of souffle. I'm not someone who orders something else when some chocolatey thing is on the menu (which it was). But I was glad the waitress convinced me to try it. Really good. and the Muscat dessert wine she recommended went really well with it.
Overall, an excellent meal for one at the counter.
Thank you for the recommending it to me!
