We were there for about ten minutes between 7-7:10. Walked all around but didn't see any obvious FT-types - unless you were sitting at the first table off to the left from the main entrance.

We ended up going to Africa Queen for dinner - it's an Ethiopian (I think) restaurant a few blocks away at that big intersection SW of the Hbf. Quite tasty food and excellent service from the owner (or someone) who spoke great English.

BTW, the Holiday Inn Express on the G-Strasse is not really all that convenient to anything - it's a good 15-25 minute walk to the Hbf.
