Catering Stations - Too Little?

FH and I are going for a very casual format to our reception with a catering menu based in comfort food. We are currently trying to lock down a caterer and have been considering doing stations as the format to keep it casual throughout the night, as we don't want a formal set meal. We are also trying to keep our catering costs within a reasonable price range as we are paying for everything ourselves. All that being said, we are currently considering a menu from a company that includes 3 appetizer options, a sliders bar with 2 protein options, a loaded fry bar which includes 2 types of chili among other toppings, and a salad bar. My question is... does that seem like enough food for a dinner time reception? Should we consider adding another station? Or swapping out the salad bar for something more? Like I said, we are trying to keep the cost minimal but I also don't want anyone starving and wanting to leave early just because we didn't provide enough food.
