I would like to go starbucks for a meeting
spiv005 is right, there are many options for Starbucks at BGC.
The one in Highstreet is nice and you can choose to walk around afterwards. My favorite Reserve Starbucks is at Central Square, 2nd floor of the mall. Reserve coffees are pour over specialty coffee and it comes with a cookie, although the cookie became smaller than a month ago :))
32nd st Starbucks is the easiest to find with ample parking. Near St. Lukes
