Don't know why this question would be showing up in ONLY the Landscape Design forum ...? Anyway, since you have a balcony, if you want to grow something in a pot, I would consider annuals ... anything that is heat tolerant. If you want something that is tall and provides some quick screening, consider corn. Yes, plain old corn. It's quick growing and very attractive in a pot. Plant seeds 3" deep. If too shallow they will fall over when young. 8 seeds per 15 gallon container.

If where you eat is bar height and the floor is hard surface, I'd recommend getting a nice drafting stool (on casters) with arms as is much more convenient and comfortable than many/most common bar height stools. Most have of them have no wheels so must be dragged. Many don't swivel so getting in and out is harder. Arms add comfort.
