Had a quick workday lunch at 1890. The restaurant wasn't at all crowded and, likely as a result, service was relatively quick. The lunch menu featured a very hotel-like (which is appropriate, of course) selection of salads, sandwiches, burgers, and some dinner entree-like fish and steak items. I ended up having the English Style Club Sandwich, which is turkey, smoked bacon, a fried egg, and Dijon mustard. The smoked bacon didn't particularly stand out, but I think the fried egg and Dijon mustard tied the sandwich together well enough. The dish comes with a choice of a cucumber salad (I think) or fries. The fries were pretty decent--not as oily as one might expect.
The service was friendly and efficient. Prices seemed a little bit high for what we got--lunch for 2 (sandwiches and iced teas only) with a generous tip totaled $40. I wouldn't say this is a big "power lunch" place but you'll definitely see a number of tables full of suits. Because it's tucked away in the Hyatt Hotel, which itself is a little camouflaged in the Arcade, I like 1890 as a low key place to get away for a little bit and enjoy a decent meal.
