Whenever I have an errand to run near Sendlinger Tor, I find an excuse to head over to Bottles & Glashaus, a store that sells, well, bottles and glasses. Even if you don't get excited by that kind of thing, it's still worth a look.
They've got it all; apothecary jars, corked bottles, weck jars, wine, sekt and cocktail glasses, beakers. I can spend hours in there trying to rationalize why I need ten mini-glass moonshine jugs.
I did a little home re-organization and moved all my spices out onto a shelf to save room in our micro-kitchen. So now I have a legit reason to swing by B&G more often (oops! we need a jar for the dill!)
If you're wandering around the area it's a great place to cheaply and easily kill an hour.

It's a little hidden, follow Josephspitalstraße toward the end.
P.S. I also just saw that they ship Europe wide and have really great rates within DE.
