Gina,
Yes, the menu appears to have been scaled down, especially from many years ago. But, if you compare the BW eateries (and this is IMHO only):
Big River is more about beer, less about food and service (at times).
ESPN is a sports bar atmosphere, with pub style food as well.
Flying Fish is a more costly meal, but in a pretty nice atmosphere.
We think Spoodles beats both BR and ESPN for food quality, and is more affordable than FF. If nothing appeals to you on the menu, then you should consider the other options, but even with the limited menu we have always been able to find things to choose from.
