In what some people around here call "Robert Mondavi's monument to himself", you'll find the much ballyhooed Copia. There was much local turmoil when the center was being built (traffic & land use issues), and now they're doing their best to actually INCREASE the amount of traffic, as the attendance numbers have been unfavorable as of late.
Perhaps it has to do with the overpriced admission ($12.50 for adults; $10.00 for seniors and $7.50 for children). Perhaps the lack of attendace stems from the almost-comically snooty attitude coming from the people working there. Maybe the low numbers are a sign that maybe a museum about food and wine is just too limited to bring in enough people.
To Copia's credit, they are changing to adapt (except the admission). The on-site restaurant, Julia's Kitchen (as in Julia Child) has recently changed management and promises to be more "down to Earth", which was MUCH needed. Copia also has been hosting the Farmer's Market on Tuesdays, and will be hosting a slightly expanded Saturday Farmer's Market this spring. For the first time ever, the Mustard Festival was held on Copia's grounds this year, and the crowds were actually too much...so there seems to be a delicate balance that needs to be worked out in regards to foot traffic.
Second-run movies and musical performances are also regular events at Copia. Again, the tickets for these are not a great bargain.
While I would recommend Copia for the visitor who fancies him/herself a food or wine enthusiast, I would honestly say keep this off your list if you are with children or have only a marginal interest in the whole "fine food & wine" culture.
