semo233's kitchen sounds like mine. Our house came with a two-tier peninsula-style countertop that separated the kitchen from the family room. We didn't like the setup - the top tier was narrow and anything tall placed on the upper level blocked the view from both sides. If a dish/glass got knocked off the upper tier, it shattered on the lower tier. I'm not tall, so I had to climb up onto the high bar stools and it was not comfortable to sit to talk to someone in the kitchen. If you sat on the kitchen side, you couldn't see over the upper tier to talk to someone in the family room or even look at a TV show while you did dishes.
We had the upper tier removed and a level granite countertop with an overhang installed. Fortunately, it didn't involve relocating any plumbing, but we had to move the disposal and dishwasher switches to the nearby wall. We kept the same base cabinets, so we have plenty of storage on the kitchen side of the counter. Target had the perfect counter-height stools on clearance. We love the setup and use it for breakfast, homework and sometimes dinner. We usually eat dinner in the dining room, but if we want to watch a special on TV, we'll eat dinner at the counter. That keeps my family room cleaner since they know not to bring food/drink in there - no need with the counter.
The upper tier was 18" higher than the lower tier and they framed it with 2"x4"s. The top tier counter was only about 18" wide, so it wasn't practical for anything bigger than a plate.
