Reporting back after my trip (too late for BrewArk — sorry). I agree with the comments on the Frog Pubs. I never made it to La Fine Mousse, unfortunately. I still recommend La Cave à Bulles. But overall, in my estimation, the beer scene hasn’t changed much since I was there four years ago.
Belgiany beers are available from most cafés, brasseries, etc., usually of a Belgian Wit or Pale bent. But you’re better off having the outstanding and inexpensive wine. The standard Fischer and Kronenbourg beers you can get in most places are to be avoided, in my opinion, unless you’re parched and need a refreshing quaff from all the walking. They’ll slake your thirst but, on contemplation, are pretty bland.
I did have a Fischer Réserve Ambrée in Strasbourg (earlier in the trip). It was like a Belgian Pale, with some pleasant toasty and biscuity malt notes, but it finished very sweet (hard to finish the half liter pictured on the right below).
