I've eaten there several times and only ate at the table once and the rest of the times, I've sat at the bar. There's an area where you can go down and stand in front of the window and you're not blocking anyone at a table. There are also tables in the bar area if you would feel more comfortable eating there so you're not taking a prime table and not eating an entire meal.
I don't think they can "make" you order a meal if all you want is appetizers or dessert.
