Pleasant without being expensive, but more importantly just a few mins walk from an S-Bahn/U-Bahn station - Berlin is huge, so you'll likely be needing public transport anyway to get around. That said, the hotel is very central and almost equidistant to the Reichstag, Potsdamer Platz, Brandeburg Tor, Holocaust Memorials, 'Museum Island', Hackescher Markt, Fernsehturm etc. etc. Although a rail travel pass will be better for all those, unless you really like walking - but if you do fancy walking, this spot is like the 'hub' in a wheel, with most places 15mins walk in any direction.
There's one of the 'Blockhouse' chain restaurant nearby on the same street, which serves all the basic burger, steak & veg food you're talking about, plus the nearby Freidrichstrasse train station - like all stations in Germany it seems - has a proliferation of casual eating outlets.
Aside from everything mentioned above, go to the abandoned Templehofer Airport - scene of the airlifts and a fun, expansive space to roam around.
As mentioned, the Reichstag tour is a must & free, but you'll need your passport & a prior online booking.
For the Berlin Wall, the best remaining bit is the 1,316m long East Side Gallery.
The Fernsehturm offers incredible views.
Berlin is brilliant.
Edit: There's (quite deliberately) nothing there to see now except a nondescript car park with a single small sign, but look up where the Fuhrerbunker was. Nothing much to see, but worth a look if near the Brandenburg Tor.
