Soho is right by my office, so I find myself there occasionally. Typically more than intended, and especially when we need a more neutral lunch spot. That sounds cruel, but it simply is what it is: a hotel restaurant & bar.
In the category of hotel restaurants, the selection is wide and diverse, and the quality is certainly better than others. However the price is definitely marked up for the audience (hotel guests have to eat somewhere, right?), and I have experienced issues with consistency.
Faults aside, the locale is convenient, and I do appreciate their diverse selection (some fusion-inspired items, vegetarian options, fun sides, etc.). Make sure to check the back of the menu for the weekly specials. Each week the chef(s) will come up with 5ish unique items. These are certainly the gems of the menu, and often contain ingredients not found in the standard menu.
