阅读短文，判断下列句子正（T）误（F）。

　　Carol's Cafeteria has the most delicious food in town.  But there is one

problem.  It's not in the busiest part of the town.  It takes about fifteen minutes to

walk there from school. My friends and I usually go to Lenny's Lunch Bar.  It's

closer and the food is really good.

　　The people at Lenny's are also friendlier than those at Carol's. In fact,

Lenny's is the friendliest place in town. They have the biggest hamburgers and the

best salads. But their pizza is pretty bad. You should never have pizza at Lenny's!
