I've been looking through the list of restaurants participating in Restaurant Week L.A. which runs January 25-30 and February 1-6 (Saturdays not included.) There is tiered pricing, unlike in San Francisco where there was only a difference in price between lunch and dinner, not dining establishments. Lunch is $16, $22 or $28 and dinner is $26, $34, or $44, depending on whether it is a deluxe, premier, or fine dining establishment.
I can enthusiastically recommend the food at a number of the restaurants on the list, such as Drago (one of the best high-end Italian restaurants at which I've eaten), Angeli (an excellent and reasonably priced restaurant about which I've written before), Roy's Hawaiian Fusion Cuisine in Woodland Hills (which surprised me and was a hit with both my husband and son as well--and which has a tasting menu throughout the year), Patina, Border Grill (owned by televsion's Two Hot Tamales, but I liked the food a lot anyway), Lowry's and Ruth's Chris Steak House (although I no longer eat red meat, I remember it well.)
I'm somewhat surprised by the appearance of the Daily Grill, which I don't really care for and Gladstones (at best o.k., but they do know how to wrap leftovers), identified as deluxe dining--in someone's dreams. Katsuya may well be a cheaper dining experience alla carte than the premier three course price. I was stunned by the selection at a $$$ tapas restaurant. $44 gets you three tapas dishes at The Bazaar by Jose Andres, considerably more than it cost the last time I went out for tapas.
The participating restaurant I would most like to try is Gordon Ramsay's London West Hollywood, which is one of the $44 selections, but I'm not sure about the menu choices. I'd have to go through the list and menues before I'd make any other choices. With our booked schedule, it is unlikely we'll actually get a chance to participate this year unless we make an early-evening reservation for the night we're going to see Minsky's next week.
