Couldn't wait to try this new restaurant. My friend and I first ordered a crab stuffed portabello mushroom -- delicious and rich. Our big disappointment came with the Betty's signature salad, which contained mixed greens, candied nuts, pears and gorgonzola. The pears were canned! To me, a restaurant serving pears from a can is unacceptable.
I really wanted to like this place, but doubt I will go back.
Output:
NEGATIVE
