Is it customary to have food at a bridal shower and should men be present?

I came away from my cousin's bridal shower perplexed. I always thought some food was part of the celebration. I don't mean it had to be a 10-course meal, maybe just some cake and coffee would be provided for the invitees and maybe even some party games. All she did was open her gifts and cards and thank everyone for coming and that was the end of the shower. Also, her fiance and some of his friends and relatives were present, which took me aback somewhat. The other attendees seemed to take that in stride. Is this sound like a customary bridal shower (in USA)?
