I guess the first question for the solo tasting menu meal is whether you want to eat at the bar/pass or whether you are comfortable doing it at a table. I would find it somewhat odd to do the solo meal at a table, but this is a preference and perhaps a weird one, so I will not judge. If you are comfortable with a table, Edulis is probably the choice. Not that it's "better" than Alo - the cooking is not as precise, it's more rustic - but it is unique. I can't say I've been anywhere quite like it in North America. The cooking is a modern interpretation of fairly European country cooking with an intense focus on ingredient quality. It's very special, but also cozy and romantic and has no bar.
The pass at Alo is the natural option, though the price point is a bit high. It's very good, though the food itself will be something you've seen before, it is a very good version of food that you've seen before. It's the consensus best restaurant in town, which also means that it's the restaurant that most resembles an international modern fine dining experience, though the food is mostly French with Japanese and Italian touches here and there. It's pre-New Nordic, if you will. This may sound tepid, but it's not. Alo is a very good restaurant.
Actinolite is kind of the opposite of both Alo and Edulis. Highly Canadianized New Nordic-ish cooking in a further flung neighbourhood in a more rustic room. Recent meals here have been very good. The food, despite the New Nordic touches, is actually very comforting. It's further afield, but you can eat at the bar and they are at the top of their game.
Canis is also doing some nice things. My last meal there had some misses (an inexplicably sous vided short rib in an onion broth) and some home runs (the roasted duck) and it generally fits nicely into the progressive tasting menu in a small restaurant with natural wines space. The duck itself is worth the visit.
There are the thoughts.
