M：Have you been to any good restaurants lately? I’m looking for somewhere special to take my girlfriend on her birthday.
W：Well...My husband and I tried Clancy’s Seafood Bar last Sunday.
M：Oh，really? I read in the local paper last week that the food and atmosphere there are superb but the price is a bit on the steep side.
W：It’s true that the food is really very good，and the price is a bit expensive on the other side. However，the place is a bit too formal. I couldn’t really relax there.
