I come form the hard nose type of upbringing and do the same with my children. When food is presented, he child is to eat with no toys at the table. If he doesn't eat, he goes hungry. Take him down from the table but don't let him go to play. Put him in his room. AND do not give him snacks or anything inbetween regular scheduled meals and snacks. I'm sure this has nothing to do with not being in the high chair, but rather "that age" where they become picky eaters. When he gets hungry, he'll eat.
Save his drink for last so he doesn't fill up on that instead. Serve his least favorite foods first on the plate, in courses. Once he hits 2, you can give him half a Flintstone Complete vitamin to supplement anything he misses until he gets over his picky stage, which could last quite some time. But again, don't feed him inbetween meals trying to fill him up from what he misses at meals. This will confuse him and will hinder him eating at meal times (breakfast, morning snack, lunch, afternoon snack, dinner). Any doctor will tell you to do your best in offering him balanced meals and he'll eat when he's hungry.
