@firefly,
Firefly, I'm sure your sweet puppy will be welcome in the café. More and more restaurants have become dog friendly. I think that people who visit restaurants with their dogs make sure to watch them carefully to make sure they don't leave any unpleasant messes without being cleaned up.
I've taken my dog, Sally, to a local restaurant and even though she is a playful Jack Russell terrier, she is very will behaved and a lovely companion.
I'll be in line to pet your little guy as soon as the others have finished.
