The menu offers many of the entree choices you'd expect in a French bistro. The menu isn't large, but my fellow diner and I enjoyed everything we tried. I ordered the onglet (hanger steak) with a shallot and wine sauce. The beef was of a high quality and properly cooked, and it was superbly complimented by the sauce. The wine list is large enough without overwhelming a diner. Bottles are priced fairly; some are expensive, but most are within reason.
The ambience of Bistro Cacao has a Victorian style without being too frilly. It's especially nice for people who are taking someone out on a date. Couples can dine seated on nice wing chairs from tables flanked by classy red curtains. One complaint I have is that the restaurant's menu is choices are not accessible via its website.
The bistro has plans to open a wine bar soon, although it's not clear to me where within its current premises, the wine bar would be situated -- so stay tuned.
