I recently picked up this great little shopping guide – Guided* Graz . It lists independent small businesses which specialise in fashion, furniture and jewellery. As well as food & drink, cultural tips and places to stay. The focus is on the city center as well the Gries / Lend area, so very easy to stroll around and check them all out. Plus the guide is in German and English. I found mine at the Kunsthaus( with the leaflets downstairs by the lockers and bathroom) but you should be able to find it in small shops & cafes, museums or at the tourist office.
You can also download a copy here or visit their website . where they have ‘ shops of the month’, ‘insights’ (small interviews) with local business people, ‘city maps’ of all the shops and ‘events’ focusing on art & design.
If you happen to visit Vienna, you can check out their Guided Vienna recommendations.
