I am in town visiting and stopped at Shea for lunch. I actually had a breakfast sandwich/bagel even though it was 1pm (they said you can have breakfast anytime!). 
The service was great and it was very cute inside. There are tables and they have free wi-fi so it would be a great place to meet clients for a casual meeting.
They also have a drive-thru if you want to grab a quick cup of coffee.
