I don't know sth side too well. Sorry..

But we had our reception in a bowls club and had a buffet meal.. But in a club you would be able to have their normal bistro menu, and as you have a booking, they would be aware and able to plan for the 'extra' patronage. Some restaurants would be hesitant (and expensive) as to accomodate that amount of people for one gathering, they are turning away other patrons.. Cause with a wedding, you don't generally eat and go, and they would be wanting to recoup the costs of the 'lost meals'.. But a club has the space, ifywim..
